To all whom it may concern:

Be it known that I, FRIEDRICH PANSE, a subject of the Em eror of Germany, and a resident of 43 Heinickestrasse, Essen-on-the- Ruhr, Germany, have invented certain new and useful Improvements in Universal-Joint Couplings, of which the following is a specification.

The-present invention relates to a universal joint coupling which is very simple,- is of compact form and is capable of great resistance.

One embodiment of the in'vention is shown in the accompanying drawing by way of exam le.

igure 1 is a side view of the coupling, partly in section; Fig. 2 is a section on line 22, Fig. 1, looking from the left, some parts being shown in elevation; Fig. 3 is a view corresponding to thatshown in Fig. 2, the parts being shown in a different position; Figs. 4, 5 and 6 are detail views, the details being i hown in" the view and position shown 'in i and B are the two shafts which are to be con led together and which are provided heads A and B. A coupling member sists of two wings C and C which are rigidly connected one with the other and each of which forms the sector-shaped portion of a rotary member with plane side faces. The cylindrical guide surfaces c of the Wings extend over a central angle of about 120 and belong to cylinders WlllCll have their axes intersecting in a point and at right angles to each other. The guide surfaces are arranged in such a manner that one of them is located entirely to one side and the other entirely to the other side of the plane containing the two axes of the cylinders. The sides of the wings C and C are provided with arcuate guide rails c which are of rectangular cross section and which are curved in an arc coaxial with the guide surfaces a The heads A and B of the two shafts are provided with recesses which have the circumferences of their walls corresponding to those of the wings O and C toform cylindrical guiding surfaces. In these recesses the wings C an O are swingingly guided. The recesses in the heads A and B are rovided with arcuate grooves a and 6 (Figs. 4 and 6) which correspond to the rails 0 When the win s engage the heads, the grooves and the rai s lected in such a manner that theaxes of the rotary members, of which the recesses a. a and b 6 form a part, intersect the axes of the shafts A and B at right angles, and the cen tral angle determined by the recesses is smaller than 180. The size of the central angle determined by the rails c is selected in such a manner that the rails c are not any longer in effective engagement with the corresponding grooves a. 1n the shaft head A when the shaft A is turned from the position in "which the axes .of the two shafts are in alinement about the coupling member C (assumed to be stationary) and the other shaft B (also assumed to be stationary) until the head A abuts against the head B of the other shaft (Fig. 3). The same result is ob- .tained when the shaft B is turned about the coupling member 0 and shaft A. By reason. of this arran ement it will be understood.

so I

that the coup 'ng" can be easily disconnected and connected.

Particular attention is drawn to the fact that no bolts or screws are necessary for-connecting the parts of the coupling and that the coupling can be coupled and uncou led without the use of tools of an kind. urthermore it is apparent that al the parts can be constructed in very strong and compact forms without giving the coupling too great dimensions.

It is not necessary that the axes of the rotary members, to which the uide surfaces 0 c on the wings C and C be ong, intersect each other in a point; they may, of course, be spaced from each other 1f only their directions are at ri ht angles to each other. It is evident that t e guide surfaces 0 a may be replaced by any other suitable rotary bodies having faces which serve as guide surfaces.

Having thus described the invention, what is claimed and desired to secure by Letters Patent, is:

1 The combination of a pair of shafts having undercut recesses therein, and a coupling. member swingingly mounted in said shafts, the guiding surfaces of the coupling member being laterally enlarged at their peripheries and tting in said recesses whereby the cross sections of the recesses in the shafts and of their working positions, the length of the interlocking positions of the guiding surfaces of the coupling member being such that at least one of the shafts can be separated from the cou ling member by turning the shaft about t e aXis of its gulding surface on the coupling member.

3. The combination of a pairof shafts having undercut recesses therein the central angle of each of which does not exceed 180, and a coupling member swingingly mounted in said shafts, the guiding surfaces of the coupling member being laterally enlarged at their eri heries and fitting in said recesses whereby t e cross sections of the recesses in the shaft and of the guiding surfaces on the coupling member interlock to prevent the shafts being separated from the coupling member when in their working positions.

4. The combination of a pair of shafts having undercut recesses therein, and a coupling member swingingly mounted in said shafts,

separated from the coupling member w en in the guiding surfaces of the cou ling member being laterally enlarged at then peripheries and having their axes at right angles and intersecting, the guiding surfaces on the cou lin member fittin g in the recesses in the sha't w ereby the cross-sections of the recesses and the guiding surfaces interlock to prevent the shafts being se )arated from the coupling member when in t ieir working positions.

5. The eombin ation of a coupling member composed of a pair of sector shaped vings arranged at right angles to each other, arcuate guide rails arran ed on the sides of the Wings, and a pair of s iafts recessed to fit the Wings and its rails and movable to positions beyond the ends of the rails to permit them to be separated from the coupling member.

6. The combination of a coupling member composed of a pair of sector sha ed win s arranged at right angles to each ot er, gui e members arranged on the sides of the wings, and a pair of shafts recessed to fit the wings and its guide members and movable to positions beyond the ends of the guide members -to permit them to be separated from the coupling member.
